SPOOL FOR TEXTILE MACHINERY.

SPECIFICATION forming part of Letters Patent No. 449,914, dated April'7, 1891.

Application filed September 6,1889. Serial No. 323,139. (No model.)

To ILZZ whom it may concern:

Be it known that 1, JOHN E. PHILLIPs, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Spools for Textile Machinery, of which the following isa specification.

My invention consists of certain improvements in the construction ofspools such as are used in connection with carding-machines, spinningmules or jacks, and like textile machinery, and especially to spoolswhich have projecting trunnions or journals at the ends, the objects ofmy invention being to simplify and cheapen the construction of spools ofthis character, to provide for the ready removal of the screw-shankswhereby the heads are held in place, and to prevent splitting of thestick or body of the spool at the ends when strain is exerted upon thespool or upon the heads of the same. These objects I attain in themanner hereinafter set forth, reference being had to the accompanyingdrawings, in which- I Figure 1 is alongitudinal section, partly inelevation, of a spool constructed in accordance with my invention. Fig.2 is an end view of the same. Fig. 3 is an end View with the head of thespool removed. Fig. 4 is an enlarged transverse section on the line 1 2,Fig. 1; and Figs. 5, 6, and 7 are detached views of parts of the spool.

A represents the cylindrical body or stick of the spool, and B B theopposite heads of the same, which are composed of metal, vulcanizedfiber, or like material, each head being longitudinally confined to thebody by means of the flange a of the screw-stem D, which is adapted to athreaded opening in the stick or body of the spool, and has at the outerend, beyond the flange a, a projecting journal or trunnion 1), wherebythe spindle may be mounted in suitable hearings in the machine inconnection with which it is to be used.

The screwstem D, with its flange and proj ecting trunnion, constitutes,as shown in Fig. 5, an integral structure, which can be cast ofmalleable iron or steel, so that the construction of this portion of thespool is materially cheapened and simplified as compared with a spool inwhich the flange a is separate from the screw-stem, and is adapted to athreaded portion of the same adjacen tto the trunniona constructionwhich has heretofore been employed.

Vhile the stem D maybe screwed directly into the wooden body or stick Aof the spool, such construction is objectionable, because of thediificulty which has been experienced in unscrewing the stem from thebody of the spool when it is desired to remove or replace the head ofthe same, the firm hold taken by the wood upon the thread of the screwcausing the stripping of the wood, and thus preventing the screw-stemfrom taking a proper hold when it is again inserted. I therefore, afterboring out the body or stick of the spool, insert therein a split tube(Z of sheet metal, such as shown in Fig. 6, which tube may, in the firstinstance, be prevented from turning by means of spurs or barbs f, formedthereon and engaging with the end of the spool-body, as shown in Fig. 8.hen this tube has been inserted, the stem D is screwed into the same,the effect of this movement being to slightly expand the tube and formin the same a screw-thread corresponding with that of the stem, the tubefinally forming a threaded segment of substantially the character shownin Fig. 4. This tube forms practically a metallic nut for a portion ofthe screw-stein D and permits the ready removal of said stein when it isdesired to remove or replace either of the heads of the spool.

.To strengthen each end of the stick or body of the spool, a metal ringF is let into an annular groove in each end of the spool, this ringhaving internally projecting lugs g, which bear upon the stem D beyondthe threaded portion of the same and close to the 'head 13, so that anystrain upon the head or stem is transmitted to the inserted metal ring,thus preventing the splitting of the stick or body of thespool, whichmight otherwise result.

The internally-projecting lugs g are wedgeshaped, as shown in Fig. 7, sothat the ring can be driven into the grooved end of the spool-stickwithout necessitating any mortising of the same.

Projecting longitudinally outward from the ring F are lugs 43, whichenter recesses or openings in the head of the spool and serve to preventthe turning of the same independently of the stick or body.

Having thus described myinventionl claim and desire to secure by LettersPatent 1. The combination of the stick or bodyof the spool and itsopposite heads with the screwstems having head-retaining flanges andwith sheet-metal linings for the bore of the spool, into which the headretaining stems are screwed, substantially as specified.

2. The combination of the stick or body of the spool having recessedends and opposite heads, the screw-stems with their head-retainingflanges, and the rings adapted to the reeesses in the ends of the stickor body of the spool and having internally-projecting lugs bearing uponthe stems aforesaid, substantially as specified.
